The noise of “racism” overcomes your well thought-out realities and your exposition of the real problem. Maybe what Obama said about “you can’t change Washington from the inside” is true of the Republican Party on this issue. Somehow a way must be found to have what you have stated heard.People only hear “bumper stickers” it seems.Something like, “importing slave labor much?”
We can look back to the early 1900s when finally a coalition was put together to limit legal immigration. It consisted of business, the labor unions, and immigrants. Our slogan could be "American jobs for American workers." The people hurt worst by our current immigration policies are immigrants, Hispanics, and blacks. Blacks and Hispanics have the highest unemployment rates. There wages and jobs are being depressed by a steady stream of cheap, exploitable labor. Business is privatizing the profits and socializing the costs, which are enormous.
The problem will get worse if more and more white collar and professionally skilled immigrants come in and hurt heretofore insulated US college graduates who have unemployment rates of 4%. There will be a growing dissatisfaction among the educated as they feel the effects of immigration. They will not be able to find jobs or take jobs that are not commensurate with their education. And they will have the irritant of having to pay off huge college loans.
